4 When magma cools and crystallizes this type of rock forms.
5 When the melting point of the minerals in a rock are reached ______________ will form.
6 A rock formed from cemented pieces of preexisting rock is called a ______________ sedimentary rock.
7 Magma that cools in the ground will form an _________________ igneous rock.
8 When rock is exposed to great pressure the minerals can separate into bands or layers to create a _________________ metamorphic rock.
9 Some rocks form from the minerals in water precipitating (coming together). This type of rock is called a ________________ sedimentary rock.
10 When lava cools at the surface of a volcano or at a mid-ocean ridge, an _________________ igneous rock will form.
11 When a rock forms from the remains of living organisms it is called an organic or _______________ sedimentary rock.
